Win 10 build 15002 - MultiGPU doesn't work properly on AMD ? - Microsoft Community

i've setup running 6-8 gpus , working reliably under win10 aniversery update.

i loaded up new prerelease win10 creator (15002) , , cannot seem see beyond 2 gpus. if put in 6 gpus,  2 of them detected , has drivers loaded.  other 4 gpus "missing", meaning don't appear in device manager (i.e. don't get  icons then under  "generic multimedia devices". )  win10creator loads amd 21.xx display driver. scan new devices doesn't make missing devices re-appear.

if uninstall amd drivers, , "scan new hardware", of sudden 6 gpus appear as  "generic multimedia".

if try load the latest driver amd website (which same 1 using original win10 aniversary testing) 1 of 2 kind of behavior.

(a)   it sees 2 gpus, same behavior listed above. . 

(b)  see 3 gpus out of 6. if gets here, whole desktop corrupt (except 1st one, , so, it's glitching every 2-3 secs)

(note. each gpu connected 2 displays. same setup previous win10 aniversary testing, boards/ connectors/ monitors work in setup).

i tried several different amd boards, , various different results, wasn't able (yet) come with 4 gpus , beyond 4 lit displays + (1 or 2 displays lit, have various issues.  displays (usually first one) seems glitching whenever there's activity clicking on start menu.

is there settings in win10 creator, can try, perhaps fix issue ? 

anyone else having similar issue me ?
